SPINDLE. I

Be itknoivn that I, CHARLES S. FOSTER,

a citizen of the United States, residing at Central Falls, in the county of Providence and State of Rhode Island, have invented certain new and -usetul Improvements in Spindles, of which the following is a specification. l

My invention relates to spindles, and more particularly to a sleeve whirl spindle.

It has been customary in the ordinary construction of sleeve whirl spindles to provide the bolster case with a hook; or other device, to extend oveftheupper portion of to prevent the lifting'ot' the spinthe whirl, die from its bearing during the dot'fing operation. The use of a hook, or similar deover the upper portion of the whirl, as stated above, is objectionable, in that the hook acts to catch lint, and also interferes with the band passing around the whirl.

The object of iny invention is to do away with the retaining hook or device a'bo *e re ferred to, and to substitute therefor a spring hook or device, attached to the bolster case at one end, and adapted to extend within the lower part or the whirl at its other end, and to extend over an inwardly extending lip or flange on the lower part of the whirl. The pushing in of the upper end of said spring hook will release its engaging end from thewhirl, to allow the spindle to be raised and remo ed from theholster case.

My invention consists in certain novel features of construction as will be hereinafter fully described.

Referring to the drawing 1-Figure 1 is front elevation of the spindle, and its sup porting case embodying my improvements.

In the accompanying drawing, 1 is the spindle, having a whirl 2 thereon.- The whirl 2 1s recessed 111 1ts lower part, and

and whirl from the bolster of my iinproven'ients Serial No. 663,201. I

The bolster case 3 construction, and is provided with a flanged portion '3 to rest on the spindle rail, not shown, and also with a screw thread 3", to receive the binding nut, not shown.

4 is the bolster for the lower end 1 of the spindle. l. The bolster 4 may be of any ordinary construction.

I will now describe my improvements in attaching spring or device for holding, the whirl, to prevent the lifting of the spindle from its bearing,- exceptwhen it is'desired to do. so. 1

On one side of the flanged portion 3 nd preferably extending in a recess therein, is attached, in this instance by a screw 5, the lower end of a spring 6. The spring 6 preferably extends at its lower part in. a groove or recess in the iianged part 3 of the bolster case 3, and is flush with the top surface of said flanged part. end of the spring 6 is preferably bent outwardly, or made hook shape, as shown at 6', and is adapted to extend up within the opening between the lower end of the whirl, and the side of the uprightpart of the case 3, with its upper hook end extending over the inwardly extending lip or flange 2 on the whirl 2, as shown by full lines in Fig. 2.

Then it is desired to remove the spindle case 3, the spring is pushed inwardly, as indicated by broken lines in Fig. 2, and the whirl 2 is then free to pass by the hook end 6 of the hook 6, to be removed.

It will be understood that the details of construction of my improvements may be varied if desired.

The essential feature-of my a spring, combined with the bolster case, and with its upper end extending over a lip or flange on the lower part of the whirl on the spindle.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. The combination with the bolster case, and the whirl of. a spindle, of a spring, adapted to extend at its engaging end through the lower part of the whirl, and extend over a lip or extension on the inner side thereof.

2.. The combination with the bolster case, and the Whirlof a spindle, of aspiring, attached at one end to the holster case, and

adapted to extend at its free end between the bolster case and the lower end of the Whirl, and to extend, over :1 lip or extension on the whirl.

3. The combination with the bolster case, and the whirl of n spindle, of a spring, having one end attached to the bolster case, and its other free end, of hook shape, extending between the bolster case and the lower end of the whirl, and adapted to extend over an inwardly extending annular lip or flange on the whirl.

4. The combination with the bolster case free end, of hook shape, extending between the holster case and the lower end of the \Vllll'l, and adapted to extend over an inwnrdly extending annular lip or flange on the Whirl.
